这篇文章主要介绍了js函数与php函数的区别,以实例形式较为简单的分析了js函数与php函数语法及应用上的不同点,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例分析了js函数与php函数的区别。分享给大家供大家参考。具体分析如下：

在PHP语法中，函数就是语法上的结构体，不是一个变量，不能被赋值；

在JS中，函数也是一种变量，变量名就是函数名。

<html>
<head>
</head>
<body>
<script type="text/javascript">
function t(){
 return 5;
}
var m = t;//函数名即是变量名。注意，不能写成t()，加括号是表示调用这个函数。
alert(m());
</script>
</body>
</html>
Copy after login

所以，声明函数也可以这样：

t = function(参数){
 函数体;
}
Copy after login
